I was having an issue with frame rate being in the 5fps range.  Now I had tried to strip down the bells and whistles to ease processing and IO load on my pc.    I disabled the RightLight setting on the cam and the low fps didnt show up immediately but occured later after a few setting changes, opening and closing several sessions of RoboRealm, etc.
Before I bought this camera I had read about it's sensitivity to inappropriate lighting, something not exclusive to this camera but can make it do weird stuff like not tracking properly. My first effort at resolving the low fps was to turn on more lights,   made no difference.
Somewhere along the way I had made a slight change to threshold, contrast or some other in playing with the red tracking vbscript example.  That minor change in in the camera settings is what messed it up.   I went into logitechs settings and enabled RightLight  and that bumped up the fps to about 9.  Then I checked optimise frame rate for video calls and went up to 30fps
I'm still struggling to understand what all is going on with the cam  with Roborealm and methods for image analysis but I can say this for sure.  This camera is finnicky about having enough light and even more so that all the settings are properly balanced based on the light that is available.

That's certainly not unique to that camera. Its actually one of the better ones when it comes to lighting. We've had a couple folks increase shutter speed or decrease brightness which increases fps but really makes a dark image. To remedy that they use the Color_Balance module which brings the image back to a somewhat ok image but still retains the higher fps.

Unfortunately as a rule of thumb, more lighting is better. If you can get 30fps in broad daylight then your camera is probably ok. During evening or night I'd expect the fps to drop unless you tweak the settings as above.

Also remember that if you suspect RR is lowering the fps just untoggle the run button and the fps should go to the max for that current lighting environment.

The other option is to get a partial nightvision IR camera with a very low lux rating. You may have to explore the NTSC + Digitizer route for that area as most webcams assume enough lighting.
